India's first lunar spacecraft, Chandrayaan-1, has been "re-discovered" by Nasa. A new technological application of interplanetary radar pioneered by scientists at NASA’s Jet Propulsion Laboratory in Pasadena, California, has successfully located spacecraft orbiting the moon – one active, and one dormant. This new technique could assist planners of future moon missions.

ISRO lost communication with Chandrayaan-1 on August 29, 2009.

Chandrayaan-1, launched on October 22, 2008, was credited with the first discovery of water on the moon.
